    Timelines – Networked Communication

    Inception of Networked Communication: Telegraphs and Telephones (1837-1876)

    The Telegraph (1837): The evolution of networked communication began with the invention of the telegraph by Samuel Morse and Alfred Vail. The telegraph used electrical signals to send coded messages over long distances, thereby transforming long-distance communication.

    The Telephone (1876): The next significant milestone in networked communication came with Alexander Graham Bell’s invention of the telephone, which allowed for direct voice communication over longer distances without the need for coded messages.

    Radio and Television Communications (1895-1927)

    The Radio (1895): Guglielmo Marconi, an Italian inventor, sent and received the first radio signal in Italy in 1895. It was a major breakthrough as it facilitated wireless communication over long distances.

    The Television (1927): Television was the next massive leap in networked communication. The first practical demonstration of television was by Philo Farnsworth in 1927. This marked a significant advancement, allowing for the transmission of visual data in real-time.

    The Advent of Computers and the Internet (1940s-1990s)

    The Digital Computer (1946): The invention of ENIAC, the first large-scale digital computer, in 1946 marked a new era in networked communication. It led to the development of private networks within organizations and later paved the way for the advent of the internet.

    ARPANET (1969): The Advanced Research Projects Agency Network (ARPANET) developed by DARPA of the United States Department of Defense, was a key milestone. This was the first network to implement the protocol suite TCP/IP, which became the technical foundation of the modern internet.

    Email (1971): The invention of email by Ray Tomlinson in 1971 marked yet another new beginning in network communication. The “@” symbol was used for the first time to send messages to other computers in the ARPANET network.

    World Wide Web (1989): Perhaps the most transformative milestone in the history of networked communication was the invention of the World Wide Web by Sir Tim Berners-Lee. The web revolutionized networked communication, creating a global network that allowed for sharing and accessing information like never before.

    Modern Networked Communication (2000s-Present)

    Social Media (2004): The launch of Facebook in 2004 brought social networking to the masses, significantly altering how individuals communicate. Since then, platforms like Twitter, Instagram, and Snapchat have continued to redefine networked communication.

    Smartphones (2007): With the release of the first iPhone in 2007, smartphones became an important milestone in networked communication. They have provided a platform for numerous apps and services that have dramatically reshaped communication, from instant messaging apps like WhatsApp to video conferencing tools like Zoom.

    Internet of Things (IoT) (2010s): Today, we are witnessing the rise of IoT, a network of interconnected devices embedded with sensors, software, and other technologies to collect and exchange data over the internet. This has further transformed networked communication, extending its boundaries to incorporate everyday physical objects.
